According to a World Bank statistics report, “The number of deaths caused by indoor air pollution has reached 111,000 per year, and an average of 304 people die every day...†The quality of indoor environment is related to the health of thousands of households. Home pollution can sometimes be shocking. .
living room
Household appliances release ozone. Improperly designed negative ion generators, air purifiers, etc. may leak ozone when working. When the ozone reaches a certain concentration, people will have cough and headache for a short time, and they will have difficulty breathing and chest pain for a long time. Therefore, home appliances should be purchased as qualified products produced by regular manufacturers, and should be ventilated at the right time.
bedroom
Being smothered by cockroaches. Carpets, bedding, curtains, etc. tend to accumulate dust and mites, which can affect lung health or cause skin diseases and encephalitis. Therefore, these items should be cleaned frequently and exposed to the sun.
kitchen
Oil fume is easy to cause cancer. If people have long-term exposure to high concentrations of soot, intestinal and brain nerves may be harmed, and lung cancer may also occur. Therefore, always check whether the range hood is functioning properly. It is best to open the window for ventilation during cooking.
Liquefied gas is the most harmful to the lungs. Liquefied gas furnaces that are not placed in a ventilated environment are the main source of nitric oxide in the home and are easily oxidized to nitrogen dioxide, causing cough and respiratory irritation. Therefore, the liquefied gas furnaces in the home must be regularly checked for safety, and the rooms with liquefied furnaces should be ventilated frequently.
bathroom
The spray is not good for breathing. The air fresheners, disinfectants and other chemicals in the bathroom contain various chemicals such as ether and flavor. They are used in a long time and will be volatilized into the air to stimulate the respiratory tract. It can be replaced by natural "air fresheners" such as grapefruit peel; chemical products should be properly sealed; ventilation should be ventilated at the right time.
Drinking water utilities may have to consider changing disinfectant to improve water quality and meet more stringent disinfection regulations. The objective of this study was to evaluate the response of a full-scale drinking water distribution system to a change in disinfectant from chlorine to chlorine dioxide, in terms of its impact on microbiological stability and disinfection by-product formation. Chlorine dioxide residuals were consistently present above detection limits throughout the distribution system (>0.20 mg/L). Over a study period of 3.5 months, no degradation of bacterial water quality occurred after implementing the new disinfectant. Chlorine dioxide maintained total bacteria (microscopic counts) and heterotrophic plate count levels below 2 x 105 cells/mL and 1000 CFU/mL, respectively. The change in disinfectant from chlorine to chlorine dioxide led to an 85% reduction in trihalomethanes (i.e., from 30 to 5 mg/L) and a 60% reduction in haloacetic acids (i.e., from 20 to 8 mg/L). Chlorine dioxide represents a valuable tool to produce high quality water and is a strong alternative to chlorine for certain distribution systems. Key words: distribution system, chlorine dioxide, drinking water quality, disinfection by-products.
